numpy.polynomial.polyutils.mapparms(old, new)
[source]
Linear map parameters between domains.
Return the parameters of the linear map offset + scale*x
that maps old
to new
such that old[i] -> new[i]
, i = 0, 1
.
Parameters: |
|
---|---|
Returns: |
|
Also works for complex numbers, and thus can be used to calculate the parameters required to map any line in the complex plane to any other line therein.
>>> from numpy.polynomial import polyutils as pu >>> pu.mapparms((-1,1),(-1,1)) (0.0, 1.0) >>> pu.mapparms((1,-1),(-1,1)) (-0.0, -1.0) >>> i = complex(0,1) >>> pu.mapparms((-i,-1),(1,i)) ((1+1j), (1-0j))
